Description of the Related Art In a truss structure, when assembling a shaft member such as a steel pipe, a ball joint of a type in which multidirectional shaft members are gathered at one point is often used as a joint member at a node. FIG. 14 schematically shows a part of a single-layer lattice shell as such a truss structure, in which 1 is a shaft member as a truss member and 2 is a joint member composed of a ball joint. Regarding the ball joint, various structures have been developed, but it is common to provide a connection hole for inserting the end of the shaft member in the connecting direction of the shaft member and connect using a bolt or the like. Is.

足場や安全ネットを組み込んだものもある。As a method of constructing such a truss structure, a method is generally used in which support members and scaffolds are assembled and the shaft members are sequentially connected by joint members such as ball joints.
To minimize work in the air, assemble a unit consisting of multiple shaft members and joint members of a certain size on the ground, lift this unit with a crane, etc., and connect the units with joint members. There are also ways to go. In addition, some of these units incorporate scaffolding and safety nets.

部材を用いる場合、従来は、各軸部材の軸心が節点の中
心に集まるようにし、偏心をできる限り避けることで、
トラス構造物全体の剛性、強度の低下が生じないように
している。When a joint member such as a ball joint is used, conventionally, the shaft centers of the shaft members are gathered at the centers of the nodes, and eccentricity is avoided as much as possible.
It is designed to prevent the rigidity and strength of the entire truss structure from decreasing.

材及び各軸部材の加工にもコストがかかるという問題が
ある。However, at a node where a large number of shaft members are concentrated, a joint member such as a ball joint becomes large, while connection is possible by reducing the diameter of the end portion of each shaft member. This leads to a decrease in the strength of the connecting portion, and there is a problem in that it costs too much to process the joint member and each shaft member.

であり、ユニット化の利点を十分活かせないという問題
がある。Further, a large-scale scaffold is required to assemble the truss structure from each member and joint level, and at present, the occupancy cost is extremely high.
Therefore, if the work is divided into assembling the basic unit on the ground and joining them in space, it is considered that the construction cost will be significantly reduced. However, even when the units are united, it is difficult to connect the shaft members that gather at the nodes with one joint member, regarding the nodes between the units. In particular, when connecting large units, it is more difficult to connect structurally unstable units than connecting shaft members one by one, and the advantages of unitization can be fully utilized. There is a problem that there is no.

工コストの大幅な低減を図ったものである。The present invention permits the construction of a truss structure by allowing the truss units having a stable shape to be eccentric at the nodal points of the shaft members and connecting the joint members of the adjacent units. The construction cost is simplified and the construction cost is greatly reduced.

て行くことを特徴とするものである。A method of constructing a truss structure according to the present invention provides a truss unit having a structurally stable shape by connecting a plurality of shaft members constituting the truss structure with a plurality of joint members. Assembling, the truss units are connected to each other in a state where the joint members constituting the truss unit are in close contact with or close to each other, and are sequentially connected.

ある。That is, the structure is constructed by connecting and constructing a part of frames constituting the structure of the truss structure as a basic unit, and at the nodes connecting the truss units, the axes of the assembled shaft members are all 1 Rather than concentrating on points, the joint members of each truss unit are gathered, so some eccentricity is allowed. Therefore, the nodes for joining the units are usually composed of two or more joint members such as 2, 3, 4, etc. However, not all of the joints connecting the truss units have to be composed of two or more joint members, and in combination with the joints composed of two or more joint members, a single joint connected by a shaft member is used. In some cases, a node composed of a joint member may occur.

に利用することも考えられる。When the joint points are composed of two or more joint members, eccentricity occurs at the joint points, but the influence of the eccentricity such as passing the shaft center of the shaft member as the truss member on the same line depending on the configuration and arrangement of the unit is affected. It is possible to reduce it as much as possible. In addition, eccentricity at the node of the truss unit joint is expected to weaken the rigidity of the truss structure and reduce its strength, but stress concentration between the shaft members that make up the truss is reduced, and so on. There is also an element of, so it does not become so negative. In particular, when not only the initial rigidity and strength of the truss structure but also the flexibility of the entire frame is required from the viewpoint of seismic performance, it is conceivable to use this kind of eccentricity in reverse.

幅な低減につながる。By connecting the joint members at the unit joints and allowing eccentricity at the nodes, structurally stable units can be manufactured before erection, and each unit maintains its shape and rigidity. Since it is erected in a closed state, it is easy to construct. Therefore, it is possible to fully utilize the advantages of unitizing the basic unit on the ground and joining them in space, which leads to a significant reduction in erection cost.

Not only the grid but a few grids or more may be used. As the simplest one, for example, a polygonal shape such as a triangle, a quadrangle, or a hexagon, or a pyramid such as a triangular pyramid or a quadrangular pyramid can be considered. It is also possible to join truss units having different shapes or different shapes, and the truss units may be designed according to the shape and scale of the truss structure to be constructed.

For example, an upper chord member truss unit formed by connecting a plurality of upper chord members with a joint member, a lower chord member truss unit formed by connecting a plurality of lower chord members with a joint member, and a plurality of belly members connected with a joint member The multi-layer truss structure can be constructed with good workability by assembling the abdomen truss units separately with a certain size and connecting these by connecting the joint members.
In addition to this, for example, a two-stage type in which a truss unit is composed of a plurality of lower chord members and a plurality of belly members, and an upper chord member truss unit is connected thereto is also possible.
